Hi; Sorry to hear of oyour troubles. I also have a MC-7. If you can get to Las Vegas, call Bob at B&B bus conversions. If he can not help you then he will know who can help. I don" have a phone number for you. Will try and look it up and repost it. Good luck, Merle.

Maybe Clifford will jump in, as that's his neck of the woods (desert) until then maybe these folks can help http://www.greatwesttruckcenter.com/?PageData=25930 Where exactly are you, are ya'll dead in the water? There is also B&B Coach up here in Vegas, give Gary a call 702-873-4415. Please keep us posted

Another contact is; Don Fairchild -- - - Bakersfield He had a spicer 4460 for sale. He also might know some one to install it for you. Some one else on this board might have a phone number for him. Let us know how all this turns out. Good luck, Merle.

Man, I am sorry I didn't have my computer for the last two weeks. I literally just threw out a perfect Spicer 4 speed case, completely stripped, two days ago. I got $25 for it from the salvage place. I spent a morning stripping out all the gears so I could get the "dirty aluminium" price. I would have happily given it to you for fun and giggles...

A&A Diesel in Mohave Valley about 20 miles from you 65 bucks a hr fwiw 928-768-4311 ask for Andy tell him I said call

good luck

DC, first off sorry to hear about your troubles.

Second off, a little education. "Luvrbus" is Clifford aka bus "Yoda". If he says something, you can go to the bank on it. In this case if he suggest A&A, you can't go wrong with them. So you would tell them that Clifford told you to call.

FWIW I just installed an MT654 in my MC7 that previously had a Spicer 4 speed standard.

I had to install a different accessory drive housing on the rear of the 8V-71 to accept the larger ring-gear, which then required a custom-machined adapter for the smaller rear main seal to fit.

We also had to modify the rear mounts that bolt to the accessory drive housing.

My 4 belt-driven DN alternator wouldn't bolt up on the new drive housing, so it was replaced by a 100 amp 24 volt unit, belt driven off the front of the engine. Pretty much everything else just bolted up.

I replaced the 2 rear doors of the engine bay with 1 large door skinned with expanded metal, and installed a Hayden 2305 transmission cooler there. It cools the transmission well so far, but the acid test will be this winter on our return trip from Brrrrrandon, Manitoba to Yuma. I didnt want to dump the heat from the automatic into the MC-7 rads which are apparently borderline with a standard transmission.

I still have the Spicer 8844 transmission sitting here.....with a used clutch, and assorted parts. It's a long way from you.

Red-whether it be a HT740, or HT754, the high gear is 1:1. Only the 4000 series has a .74 and .64 overdrive. I looked into installing the HD4060 in my truck, but it would have been $10,000 more, and then you'd have an electronic transmission. The HT740 is probably the most dirt reliable automatic ever made. The HT754 is also reliable-but a bit more delicate because of the extra gear. Good Luck, TomC

And I thew a good one away a few months back, couldn't give it away then.

We went with an Allison 740, the best decision we could have made. It also meant a shorter driveline, which we had to have made complete new from scratch. Have put on about 500 miles since we made the swap and it runs great!

Now my DW doesn't have to listen to me talk like a sailor when I shift it!
